problems with network interface naming


Hi) I have some problems with interface naming (debian lenny)

Code:
host:/# uname -a
Linux host 2.6.26-2-686 #1 SMP Sat Oct 17 17:59:23 UTC 2009 i686 GNU/Linux
after installing ifenslave-2.6 I added virtual interface to /etc/network/interfaces

Code:
auto bond0
iface bond0 inet static
address 192.168.1.2
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.1
up /sbin/ifenslave bond0 eth3 eth2
down /sbin/ifenslave -d bond0 eth3 eth2
and added 2 lines to /etc/modprobe.d/arch/i386

Code:
alias bond0 bonding
options bonding mode=1 miimon=100 downdelay=200 updelay=200
after rebooting i got interface bond0, then i commented out all changes in configs and reboot.

Now i have problem with eth2: it has MAC same as eth3 and it has bad name

Code:
host:/# ifconfig

I uninstalled ifenslave-2.6 with aptitude, but it change nothing.
